Title: Variable oscillator and write clock generating circuit using the same
Inventor: YAMADA YOSHITO
IPC: G11B20/02
Filed: 1993-10-29
Abstract: PURPOSE:To provide the variable oscillator wide in the frequency variable range and simple in configuration. CONSTITUTION:Only when the variable reproducing speed is higher than m-fold speed, a switching means 50 is made active. When the switching means 50 is not active, the frequency is varied by using an LC element at the main body of a variable oscillator 20. When obtaining any frequency exceeding this frequency variable range, a frequency variable range extension circuit 32 is operated. When the switching means 50 is set in the active state and travelled forward, the oscillation frequency is lowered at that time by inserting auxiliary capacitors Ca and Cb by switching the device into a figure shown by broken lines. Thus, the lower limit valie of the oscillation frequency is extended. When the means 50 is travelled backward, it is switched into a figure shown by real lines, and an auxiliary inductance Lc is inserted. Thus, the oscillation frequency is increased, and the upper limit value of the oscillation frequency is extended.

Abstract: PURPOSE:To prevent a separation of a bonding pad composed of an A1 alloy on a barrier film and adhere Ti to a contact hole sidewall part by a method where a Ti film of the barrier film composed of the Ti film and TiN film and an insulated film between silicon substrates are turned into a nitride film. CONSTITUTION:On a silicon substrate 1 with a diffused layer 10 formed by introducing impurities, a silicon nitride film 2 grows by a CVD method. Next, a contact hole is formed in a desired location by using lithography and etching technology. Next, after a Ti film and a TiN film 7 are succesively formed by a sputter method, they are heat-treated and Ti acts on silicon near the diffused layer 10 to form a titanium silicide layer 8. Thereafter, an Al alloy film 9 is formed by the sputter method. Thus, as a silicon nitride film containing no boron is used as an insulated film, a close adherence between the insulated film and Ti film 6 is enhanced without deteriorating coverage of the Ti film 6.

Title: Optical encoder
Inventor: OKAMOTO HIROSHI
IPC: G01D5/38
Filed: 1985-12-06
Abstract: PURPOSE:To improve measurement precision only by the alteration of an index scale by selecting the best refraction image among refraction images appearing owing to the isolation interval between two scales and making the index scale correspond to it. CONSTITUTION:The pitch and width of slits 6 of the index scale 6 are set a half as large as the pitch P and width W of slits 4 of a main scale 3. At this time, when the isolation interval D0 between the two scales 5 and 3 is so optimized that their images are equal in light intensity, a photodetector 7 generates an output signal S0. This output signal S0 is obtained by increasing the resolution of a conventional output signal. Thus, a conventional rise in cost owing to the precise working in which the slits of the main and index scales are reduced in pitch is suppressed and readout precision is also improved.

Title: Ink jet printer and driving method for ink jet head
Inventor: MIZUTANI MICHIYA
IPC: B41J2/205
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To perform high speed printing of an image having a high density without occurrence of delaying of refilling of ink in an ink jet printer. SOLUTION: In heaters SEG1-SEG4 for ink ejection of an ink jet head, the heaters SEG1 and SEG3 are disposed near an ink supplying hole rather than the other heaters. In a high speed printing mode wherein the speed is two times of that in a normal mode, the above heaters SEG1 and SEG3 are driven by a driving cycle which is two times of that of the other. A delay time corresponding to the differences of the disposing positions of the heaters is set. As a result, it is possible to reduce thinned dots due to the high speed printing in terms of the printed result, thereby preventing lowering of the overall density.
